7 Claims. (Cl. 222-562) This invention relates to pouring spouts forcontainers for liquids having a nozzle in the top wall spaced from theside walls of the container.

In pouring the liquid from the container through said nozzle, the liquidaccumulates on the top wall of the con tainer around the nozzle whichaccumulation becomes unsightly and might interfere with the sealing ofthe nozzle by the usual closure cap.

It is an object of the present invention to provide a onepiece pouringspout of resilient material, such a polyethylene, which is readilyinserted in the container nozzle by the initial mounting of the closurecap on said container nozzle after the container is 'iilled with liquid.

It is another object of the invention to provide the pouring spout witha liaring lip to direct the ow of liquid from the container and preventdripping of the liquid onto the container top wall around the containernozzle, and the haring lip being iiexed against the mouth of thecontainer nozzle by the closure cap being mounted on the containernozzle to constitute a sealing gasket for said closure cap.

States Patent It is a further object of the invention to releasablyretain the pouring spout in a clousre cap whereby closure caps havingpouring spouts assembled therein are stored for future assembling on thefilled containers.

A further object of the invention is to provide a onepiece pouring spoutwhich is economically manufactured.

Further objects and advantages of the invention will be set forth in thedetailed description of the invention.

In the drawing accompanying and forming a part of this application,Figure 1 is a vertical-sectional View taken on the line 1 1 of Figure 2looking in the direction of the arrows of the pouring spout iitted in aclosure cap.

Figure 2 is an end view of the pouring spout and closure ccap lookinginto the open end of the closure cap from the line 2-2 of Figure l inthe direction of the arro'w with a portion of the skirt of the closurecap in section to show a protuberance on the closure cap skirt forreleasably retaining the pouring spout in the closure cap.

Figure 3 is an elevational view of the closure cap.

Figure 4 is a top view of the portion of a container arranged with anozzle having the pouring spout applied thereto.

Figure 5 is an elevational view of the portion of the container shown inFigure 4 and showing the closure cap having the pouring spout releasablyretained therein in position to be initially mounted on a filledcontainer.

Figure 6 is a view similar to Figure 5 showing the closure cap fullymounted on the container nozzle and the pouring spout fully inserted inthe container nozzle with the pouring spout lip liexed to form a sealinggasket for the closure cap.

Figure 7 is a View of the top portion of the container in pouringposition with the closure cap removed and the pouring spout in conditionto direct the flow of the contents of the container.

Figure 8 is an elevational view of the pouring spout.

The present invention is particularly adapted for use with a sheet metalcontainer having a rectangular shaped body 9 arranged with a tubularnozzle 10 secured in an opening 11 in an end wall 12 of the body. Thenozzle 10 and opening 11 are spaced from the side walls of the containerbody 9 and positioned at one side of the vertical center of said body,as shown in Figure 7. The nozzle 10 is provided with screw threads, asshown in Figures 5, 6 and 7. The upper end or mouth of the nozzle 10 isarranged with an inwardly extending flange or shoulder 13 having adepending ange 14 extending into and spaced from the nozzle, as shown inFigures 5 and 6.

The nozzle is closed by a closure cap 15 having a screw threaded skirt16 for engagement with the screw threads of the nozzle 10 for removablymounting the closure cap on the container nozzle. It is to be understoodthat different methods of mounting the closure cap on the nozzle otherthan screw threads may be employed without departing from the scope ofthe invention.

The container is particularly adapted to contain viscous types ofliquids, such as lubricating and polishing oils and creams, and inpouring said contents from the container through the nozzle 10, acertain amount of the contents will drip and accumulate on the end wall12 around the nozzle 10.

To prevent this dripping and accumulation of the contents, there isprovided an economical one-piece pouring spout of resilient material,such as rubber or polyethylene. Said pouring spout includes a tubularbody 17 having a lip 18 iiaring from one end of the body and theopposite end of the body arranged with an external head 19. The exteriordiameter of the spout body 17 is slightly smaller than the interiordiameter of the depending ange 14 and the outer diameter of the bead 19is slightly larger than the inner diameter of the flange 14 but the bead19 is arranged with a bevelled face 20 to facilitate passage of saidbead through the flange 14 due to the resiliency of the material of thespout. The length of the spout body 17 is slightly longer than thelength of the depending flange 14 to position the bead 19, 20 below themarginal edge of the depending flange 14, as shown in Figure 6, toreleasably retain the spout in the nozzle 10 when the spout is fullyengaged in the nozzle 10 with the aring lip 18 extending from the nozzle10, as shown in vFigure 7.

In initially applying the pouring spout 17-20 to the container nozzle10, the pouring spout is fitted in the closure cap 15, 16 with themarginal portion of the liaring lip 18 abutting the juncture between theclosed end and the skirt 16 of the closure cap. The pouring spout isreleasably retained in the closure cap by inwardly eX- tendingprotuberances 21 formed from the material of the closure cap skirt andequidistantly spaced around said skirt and spaced from the closed end ofthe closure cap to engage the exterior of the marginal portion of thepouring spout 18, as shown in Figures 1 and 2. By releasably retainingthe pouring spout in the closure cap in this manner, a supply of closurecaps having pouring spouts assembled therein can be accumulated toprovide for a continuous and simultaneous capping of and inserting ofpouring spouts into lled containers.

To facilitate the simultaneous mounting of the closure cap 15, 16 on thecontainer nozzle 10 and the inserting of the pouring spout body 17 intothe container nozzle 10, the length of the pouring spout 17-20 is lessthan the length of the closure cap skirts 16, so that the beaded end 19,20 of the pouring spout body 1'7 is spaced inwardly from the marginaledge of the closure cap skirt 16 and the closure cap skirt 16 will rstengage the container nozzle 10 and guide the beaded end 19, 20 of thepouring spout body 17 into the opening formed by the depending flange14, as shown in Figure 5. The mounting of the closure cap 15, 16 ontothe container nozzle will move the pouring spout body 17 into thecontainer nozzle 10 with the bead 19, 20 positioned below the marginaledge of the depending ange 14 and the iiaring lip 1S flexed to ahorizontal position against the shoulder or iiange 13 of the containernozzle 10 to constitute a sealing gasket for the closure cap, as shownat 22 in Figure 6. l

The bead 19, of the pouring spout 17-20 abutting the marginal edge ofthe depending iiange 14 of the container nozzle 10 will retain thepouring spout 17-20 in the container nozzle 10 upon the removal of theclosure cap 1S, 16 from said nozzle. The resiliency of the pouring spoutlip 18 will permit said lip to pull away from the protuberances 21 ofthe closure cap skirt 16 when the closure cap 15, 16 is removed from thecontainer nozzle 10.

After the container is emptied, the pouring spout 17-20 may be removedfrom the container nozzle 10 by inserting the forefinger into thepouring spout body 17 and iiexing the lip 18 inwardly by the thumb andpulling the pouring spout outwardly from the container nozzle 10.

The closure cap 15, 16 is readily mounted on and rcmoved from thecontainer nozzle 10 without affecting the retention of the pouring spout17-20 in the container nozzle 10.

In pouring the contents from the container, the lip 18 will direct theow of said contents from the sides of the container, as shown in Figure7, and prevent dripping of the contents onto the container end 12 whenthe container is set in upright position after pouring by causing thecontents to flow down the are of the lip 18 into the pouring spout body17 and the container.

It is to be understood that the pouring spout 17-20 is adapted to beused with any type of container other than that shown and describedherein.

Having thus described my invention, I claim:
